Understood. But thanks for taking the time to respond. It's much 
appreciated, and I those are very helpful comments.

There's nothing there that would be a blocker for me for this board - 
it's destined to be a headless embedded gateway- although
from what I heard on Wayland from the Intel guys that's something I'd 
like to try if I ever manage to find the time :)
